K&J REMARKS The transfer of Multicellaesporites acuminatus Mustard & Rouse 1994 to Piriurella Cookson & Eisenack 1979 by Parsons & Norris 1999 was partly based on their illustrated specimens (pl. 8, figs. 2-5) from the Caribou Hills, northern Canada, which are much better preserved than Rouse's material. The spores of Multicellaesporites acuminatus thus are recognized as showing affinity to extant Alternaria-like morphology.

The spores illustrated by Rouse & Mustard as Multicellaesporites acuminatus, and by Parsons & Norris as Piriurella acuminata, are presumably Alternaria-like, and appear similar to Polycellaesporonites alternariatus (Kalgutkar & Sigler) comb. nov. The genus Polycellaesporonites includes forms with morphological features generally similar to modern Alternaria.
